How do cells at the completion of meiosis compare with cells that have replicated their DNA and are just about to begin meiosis?
D) They have half the number of chromosomes and one-fourth the amount of DNA.
When does the synaptonemal complex disappear?
A) Late prophase of meiosis I
Which of the following terms belongs with the words synapsis, tetrads, and chiasmata?
